I've had my 660 for a year and I'm still learning. I just bought the life time maps from the Garmin site and it says to follow the links to activate however I see no links. Since i have an order number now there must be a quick way to get my maps updated but I can't crack the code. This unit can't find my house and can't take me to town so I'm thinking and up date might be in order. I'm currently running 2012.30. Soooo the question is, how can I update my maps?. I think one problem is I can't install the plug in that's apparently required.
